Canada is removing diplomats' family members from its Cuban embassy over a mystery illness - amid fears some could be suffering from a new type of "acquired brain injury".
While there had been no new cases since the second half of previous year, diplomatic families returning to Canada had continued to report symptoms including dizziness, headaches and inability to concentrate, Global Affairs Canada said in a statement.
